At 256 lumens, this is the highest output LED tower cluster available for marine use. It combines 18 surface mount (SMD) LEDs arrayed in 6 planes for 360&#176 visibility. Proprietary PWM Constant-Current chipset results in high performance across the entire 8-30VDC range. Its 360&#176 visibility makes it ideal for wall appliques and table lamps which use the #1142 double-contact BA15d bayonet bulbs (non indexed level side pins).
